Abstract:
In this paper, a ratiometric fluorescent sensor based on double emitting carbon dots (DE-CDs) and molecularly imprinted polymers (MIP) was constructed. The sensor was successfully applied for the detection of tetracycline (TC) by using the ratio of two emission peaks of DE-CDs as the response signal, combined with the selectivity of MIP. Under the optimal conditions, the linear range of TC was 0.05-25 μM, and the detection limit was 0.03 μM. The practicality of the developed sensor was evaluated in the detection of real samples such as lake water, milk, and egg, and the recoveries were in the range of 98.0-105.2 % with RSD less than 3.2 %, which indicated that its application for the detection of tetracycline yielded satisfactory results.
